Ground Improvement Engineered Foundation Technologies provides specialty ground improvement services. We perform several grouting processes that can structurally improve the physical characteristics of a soil matrix. In general, most ground improvement work is done as either “permeation” or “compaction” grouting. For Permeation grouting, a low viscosity material is injected into the soil with the intention of the “permeating” the ground. Once in the presence of water, the material will expand and cure in place. For Compaction grouting, a higher viscosity material is injected at high pressure, physically displacing and ultimately compacting the soils.
